Last night I was at an upscale bar/lounge with some friends. The scene was 70's rock band playing in background, kinda crowded, with about 50-50 mix of people seated at tables or hovering around the bar area. I was buying my friends a round to bring back to our table and I saw an attractive girl sitting at the bar nearby (about 6-8 feet away).

We made brief eye contact 1 or 2 times, and then I smiled and she smiled in return. She seemed tentatively interested. During these few seconds I took in her surroundings, and saw that there were 2 guys protectively hovering around her, trying to make conversation. Not sure if they were friends or just some guys trying to score.

I could not see a way to go introduce myself, as the bar was crowded and there was no path I could make in-between people without asking people to move. I think I might have been able to start a converstation if either the two guys were not there, or if I had been able to nudge my way towards her, but both obstacles seemed like bad luck.

I gave up (before even really trying I suppose), got the drinks, and went back to my friends. The situation did not change when I got the next round about 45 minutes later.

Suggestions would be appreciated on how I might have better handled the situation. How would you approach a girl with two hovering guys? Conversation openers?

Edit: poor grammer
